Airtac MTF Mini Cylinder MTF25X150CM
The AirTAC Airtac MTF Mini Cylinder MTF25X150CM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 150mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac MTF Mini Cylinder MTF25X150CM
Delivering 153.6 N of net pull at 0.5 MPa, this single-acting spring-return cylinder uses air to retract a 10 mm rod and an internal spring to push it back out. The MTF25X150CM features a JIS-standard SUS304 stainless round body with riveted aluminium covers, making its overall length shorter than an ISO 6432 unit for the same 25 mm bore and 150 mm stroke. The CM round-end back cover simplifies direct rear pivoting.
Because the spring holds the rod out at rest, the cylinder fails safely to the extended position if air pressure drops. It operates on a 1/8" port with a 0.2 to 1.0 MPa range, needing at least 0.2 MPa to overcome the spring. This non-magnet SKU cannot host position sensors; adding an -S magnet enables CMSG, DMSG, or EMSG switches. Fixed TPU bumpers absorb end-of-stroke impacts across the 50-800 mm/s speed range.

Where the Airtac MTF Mini Cylinder MTF25X150CM Is Used
Tensioning Mechanisms
Uses the 153.6 N pull force to maintain strap or cable tension, releasing the load only when compressed air retracts the rod.
Fail-Safe-Open Gates
Holds a barrier open via spring pressure; air retracts it to close, ensuring the gate automatically extends open if the air supply fails.
Rejecter Arms
Stays retracted by air until a fault is detected, letting the spring snap the 150 mm stroke out to push defective items off the line.
Is the Airtac MTF Mini Cylinder MTF25X150CM the Right Cylinder?
If 153.6 N at 0.5 MPa is excessive, step down to the MTF20 bore providing 93.4 N; if more pull is required, the MTF32 offers 266.8 N. This 150 mm stroke represents the maximum standard length for the series. With a 2:1 safety margin, the 153.6 N figure translates to roughly 7.8 kg of vertical lift or a 92 N safe working load, ideal for tensioning or air-close tasks.
Choose this pull-type action when a mechanism must default to the extended position during an air loss. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion. Remember that this specific configuration lacks the -S magnet, so magnetic sensing is unsupported.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MTF Mini Cylinder MTF25X150CM FAQ
This 25 mm bore cylinder provides a net pull force of 153.6 N at 0.5 MPa and 236 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the return spring, with a maximum pressure of 1.0 MPa and a proof pressure of 1.5 MPa.
The internal spring constantly pushes the rod to the extended position, so air is only used to pull it in. If air pressure is lost, the spring drives the rod out; it cannot hold a mid-stroke load. This non-magnet CM round-end model also requires an -S variant to support CMSG or DMSG sensors.
